Earth, Moon, and Sun Table of Contents Earth in Space Phases and Eclipses Tides

5.1 Earth in Space Earth's Rotation Rotation causes: It takes _________hours for the Earth to rotate once. In which direction does the Earth rotate?

Earth’s Revolution Revolution is: It takes how long to go around Earth in Space Earth’s Revolution Revolution is: It takes how long to go around the Sun?

Earth in Space Sunlight on Earth Why do we have seasons? What would happen if the Earth was not tiltled?

Earth in Space Seasons The diagram shows how Earth moves during the year. Compare June and December in the northern and southern hemisphere.

Earth in Space Solstices and Equinoxes The diagrams show the apparent path of the sun at the solstices and equinoxes in the Northern Hemisphere. What is the sun’s path at the equinoxes and the December solstice for the Southern Hemisphere?

5.2 Phases and Eclipses Because it takes the The Moon’s Motion The changing relative positions of the moon. Earth, and Sun cause the phases of the moon. Where would the moon's face appear in each view in this diagram that shows the moon's rotation and revolution? Because it takes the Moon one month to go around the Earth, we never see the far side of the Moon.

Phases and Eclipses Moon Phases As the moon orbits Earth, its sunlit side is seen from different angles. Figure 2 on p. 192 What happens to the amount of sunlight we see from a full moon to a new moon phase? The phase of the moon depends on how much of the sunlit side of the moon we see!!!

Phases and Eclipses Solar Eclipse The diagram shows the moon’s penumbra and umbra during an eclipse. The Solar Eclipse is a special time when we are able to see the Sun’s corona!!

Phases and Eclipses Lunar Eclipse As the moon moves through Earth’s shadow, total and partial eclipses occur.

Phases and Eclipses Seasons and Shadows Identify what season it is in the Northern Hemisphere, what the phase of the moon is, and what kind of eclipse, if any, could occur.

5.3 Tides Tide Cycle Tides are caused mainly by differences in how much gravity from the moon and the sun pulls on different parts of Earth.

Tides The Sun’s Role Changes in the positions of Earth, the moon, and the sun affect the heights of the tides during a month. What is the position of the moon and where are the tide bulges at third quarter?
